When gas is released from a cylinder, it expands rapidly and the process absorbs heat from the surroundings, including the metal cylinder itself. This decrease in temperature causes the metal cylinder to become cold.

I would hazard a guess that it is an object made of metal, and in the shape of a cylinder.
A metal cylinder in Physics can serve various functions depending on the context. It can be used as a conductor in electrical circuits, as a magnetic material in electromagnets, as a container for gas pressure experiments, or as a component in mechanical systems like pistons or bearings.
You should heat the metal cylinder and cool the metal rod. Heating the cylinder will cause it to expand, making it easier to insert the rod. Cooling the rod will cause it to contract, allowing it to fit into the hole more easily.
It could sink. (The metal's density is greater than water.) It could turn into a ball of flames. (If you dropped a chunk of sodium into graduated cylinder, it would react with flames or sparks.)
The materials vary, but some of the better gaskets are composed of kevlar and metal.
The increase in volume of the water when the cylinder is added is equal to the volume of the cylinder. So, the volume of the cylinder is 21.4 mL - 15 mL = 6.4 mL. Since the metal cylinder is immersed in water, the volume of the metal cylinder is 6.4 mL.
A metal cylinder is a three-dimensional shape with circular bases at each end and straight sides. It is typically hollow and used for storing liquids or gases, such as in the case of a canister or a metal water bottle.
A fusible plug is a metal cylinder that has been threaded with a hole drilled throughout it. The plugs can be found in a variety of metals. Heated metal is used to seal the hole.
The reading on the graduated scale is taken before and after the metal is lowered into the cylinder . The second reading is subtracted from the first. This gives the volume of the metal in cubic centimetres.
